In Reply to: okay...safe dyes to add to henna and the skin it's going to go on...? posted by emmie on January 03, 2000 at 21:36:53:

A quick note first: the henna dye molecule is very small, and can
penetrate and bind to the collagen that is your skin easily at body
temperature. The molecule is only 2 carbon rings ... that's why it
works so well. Dye molecules are usually very large. That's why when
you tie-dye tshirts, you get stained, but it doesn't last the 3-4
weeks that henna does. Those molecules are too big to penetrate much.
Henna dye molecule is exactly the right size to penetrate and bind
to your dead skin, (the surface layer) but not so small that it
penetrates your living skin.

There are dyes people have tried to add to henna to change the color
:

1)the vegetable kind of dye (like is used to color Koolaid) doesn't
work well because the molecules are too big to penetrate skin cells
beyond the very top layer. These are safe for your skin. However,
They really don't penetrate your skin, so they don't stain it worth a
damn . However, they stain everything else they touch.

2)the cloth and hair kind of dye (used color wool, hair, etc. )
doesn't work well, again because the molecules are too large to
penetrate dead skin cells at body temperature. The cloth dye
molecules vary from mostly harmless to carcinogenic. The hair kinds of
dye, again, may be from ok to carcinogenic, but don't mess with them
either. They don't work well. They may do you a lot of harm. Why
risk it? That whole group is just a bad idea.

3) PPD dye may have been used on Madonna. I hope she just had Temptu.
(Especially if she was nursing at the time.) PPD molecules are
extremely small, just one carbon ring. They not only penetrate the
dead skin layer, they penetrate clear into the blood bearing layer
(living) of tissue. There, PPD creates absolute havoc on most people,
causing blistering, scarring, and can get into the bloodstream and
cause severe health problems. Link below.
